¶ Product Highlights & Drawbacks
|
Application Scenarios |
ToughPETG-HF is ideal for industrial manufacturing, automotive, electronics, medical applications, sports & outdoor gear, and food packaging. It is tougher and more impact-resistant than standard PETG and offers enhanced weather resistance and structural strength, with improved ease of high-speed printing. | |||
| Highlights | High Impact Resistance | FusRock®'s toughening technology enhances ToughPETG-HF's notched impact strength to more than twice that of regular PETG, while maintaining strong Z-axis layer bonding. | ||
| Dimensional Stability | Low warping and shrinkage with excellent interlayer adhesion. It deforms less than ABS and nylon when printing large objects. | |||
| High-Speed Printing | Exceptional material flowability allows for excellent print quality, even at extreme speeds up to 400mm/s. | |||
|
Drawbacks |
Strong Bed Adhesion | ToughPETG-HF adheres firmly to PC build plates. For large bottom surfaces, increase the initial layer height. | ||
| Nozzle Adhesion & Stringing | High flowability can lead to nozzle adhesion, stringing, and dripping. Keeping the filament dry and fine-tuning retraction, temperature, cooling, and nozzle selection can reduce these issues. | |||
| Moisture Sensitivity | Must be stored in a sealed container with desiccants to prevent degradation of print quality. | |||
¶ 3D Printer Requirements & Filament Storage Guidelines
| Nozzle Material |
Recommended: Brass Nozzle (0.2-1.0 mm) Stainless steel or hardened steel nozzles are also suitable. |
| Nozzle Heater Block Length |
≥8mm heating zone recommended. Printer must support temperatures of 240-260°C. |
| Seal the box |
No enclosure required
|
| Warehouse temperature auxiliary heating | No enclosure required |
| Heated Bed Requirements | Heated bed required: Temperature 100-110°C |
| Recommended bed surfaces | Glass, PEI sheet, or PVP glue coating. |
| Instructions for applying glue | It is recommended to apply PVP glue to print large models or models with small contact surfaces. |
| Placement of consumables |
Direct plug-in printing is not recommended (moisture-proof consumables are damp, resulting in drawing and printing failure, and the printing effect is poor). It is recommended to print in a moisture-proof box with bearings. When you really need plug-in printing, please pay attention to whether it will interfere with the material plate when plug-in some devices, resulting in printing extrusion obstruction and making the material output not smooth. |
| Auxiliary equipment (AMS/AMS2, Lite, etc.) | Support, regularly replace the moisture-proof agent or check the performance humidity, and do a good job of moisture-proofing. |
| Be damp-proof |
* After opening for the first time, immediately put it in the moisture-proof box for use, and control the humidity below 15%; after moisture in the later stage and printing quality decline, you can refer to the Wiki drying method for drying consumables. * Be sure to read the following drying notes in detail before drying! Put it in the 70-80℃ oven and dry it for 4-6h! |
| Feeding pipe method (angle, bending, etc.) | Ensure smooth feeding |
¶ Print setting parameters (slicing software setting recommended parameters)
| Recommended nozzle diameter and nozzle material | The printing difficulty is relatively moderate. Be sure to keep it dry and the feeding smooth. It is recommended to use a copper nozzle. |
| Nozzle temperature | 230-260 °C |
| Build plate temperature | 70-80 ℃ |
| Cooling fan speed | 0%-50% |
| Retraction distance | 0.4-5 mm |

¶ Moisture-proof requirements for printing and consumables
| How to place it when printing |
The recommended placement scheme is shown in the figure below:  Use it with a moisture-proof box; be sure to ensure smooth feeding. It is recommended to put it in a moisture-proof box with a bearing and use a Teflon tube to send it for printing. |
Direct plug-in printing is not recommended (moisture-proof consumables are caused by moisture, resulting in drawing and printing failure, and the printing effect is poor) When you really need plug-in printing, please pay attention to whether it will interfere with the material plate when plug-in some equipment, resulting in printing extrusion being blocked and the material output is not smooth. ( Solution) 
|
| Moisture-proof requirements |
1. Replace desiccants promptly: To avoid the situation where the desiccant has absorbed moisture but the hygrometer shows no change, make sure to replace the desiccants in a timely manner. 2. Ensure proper moisture protection during printing: Always store materials in a moisture-proof box during printing. Do not use commercially available heated moisture-proof boxes that heat the material while printing. This can accelerate material aging and may lead to further moisture absorption if water vapor cannot escape. 3. For printing with AMS/AMS2, be sure to monitor the humidity display status and replace the desiccant when needed. 4. Dry materials promptly if they become humid: If the material has absorbed moisture, ensure it is dried immediately to restore its optimal condition. |
|
¶ Material (Moisture Protection) Storage Requirements
| Short-term Non-use | 1. Place the material in a sealed moisture-proof box or a simple vacuum-sealed bag to avoid direct sunlight. | |
| Long-term Moisture Protection | 1. After placing the material in its original aluminum foil bag, expel the air from the aluminum foil bag (if possible, place a desiccant inside, such as silica gel). Then, place the bag in a vacuum-seal food preservation bag, and vacuum seal it. Store it in a cool, dry place, away from direct sunlight. | |

The heat deflection temperature (HDT) is generally related to the environmental pressure or load the material is subjected to. Therefore, according to ASTM D648 or ISO 75-1, -2 standards, the material is tested under two pressures: 0.45 MPa (simulating no applied pressure load) and 1.80 MPa (simulating an applied pressure load). This allows for a better description of the material’s thermodynamic performance. Typically, the HDT measured at 0.45 MPa will be higher than the HDT measured at 1.80 MPa. |

Interpretation of Common Material Performance Parameters
¶ Material Moisture Treatment Plan and Methods
| Drying Parameters |
• PTC Small Drying Box: 60-70°C, dry for 4-6 hours. • Small Constant Temperature Drum Dryer: Reduce the temperature by 20°C to avoid uneven temperature distribution in small equipment causing deformation (40-45°C, dry for 4 hours). If printing results do not improve after this drying, use an empty material tray to test the temperature and then increase the drying temperature as needed to prevent deformation from excessive or uneven heating. • Large Constant Temperature Drum Dryer: 60-70°C, dry for 4-6 hours. Note: Why are the drying temperatures different for various drying equipment? Click here to learn more. |
|
Precautions ⚠️ |
1. If unsure, first conduct a temperature test using an empty spool to avoid overheating or uneven heating that may lead to spool deformation. 2. Strictly follow the drying temperature and time recommended on the material parameter introduction page. 3. It is recommended to use a drum-type drying box (do not place the spool directly in front of the air outlet, as this may cause deformation). 4. When drying spools, avoid positioning them near the air outlet. 5. It is not recommended to place the spool directly on a mesh rack (use flat surfaces such as metal plates instead). 6. Be cautious of high temperatures when removing materials to avoid burns. 7. Prevent fire hazards by ensuring the safe use of equipment. 8. For drying materials, printed parts, and annealing, it is recommended to use equipment with even temperature distribution, such as a blast drying oven (ensure it is from a reliable manufacturer, as some may be inadequate for use). Do not use microwave ovens or household ovens, and avoid placing items in areas with uneven heating or excessive force, as this could cause local damage or deformation.
